... Abstract Low-pressure carburizing (LPC) is one of the most popular case-hardening processes and is applied to increase the fatigue limit of dynamically loaded components. It takes place in a pressure range between 5 and 15 mbar (4 and 11 torr) and at temperature range between 870 and 1050 deg C...

... Abstract The plasma carburizing process is basically a low-pressure carburizing process making use of a high-voltage electrical field applied between the load to be treated and the furnace wall producing activated and ionized gas species responsible for carbon transfer to the workpieces.

... distortion gas carburizing CARBURIZING is a case-hardening process in which steel parts (usually low-carbon steel) are heated to an austenitizing temperature and exposed to a carbon-rich atmosphere. Carbon is absorbed at the surface and diffuses down the chemical potential gradient to create a carbon...

... frequently used on steel components, but there are limited applications where carburizing can be used on certain nickel and titanium alloys. For steel, the solubility of carbon in ferrite is very low compared to that of austenite, so to carburize, it is necessary for the workpiece to be austenitic. Because...
